Heat is one of the leading weather-related causes of death in the U.S., resulting in an average of over 600 fatalities annually. Heat-related illnesses account for an average of 2,800 hospitalizations nationwide each year.
Summer is here, and it’s important to keep in mind that your body’s ability to cool itself is challenged on very hot and humid days. When the body heats too rapidly to cool itself properly – or when too much fluid or salt is lost through dehydration or sweating – body temperature rises. This can result in a heat-related illness or death if left untended.
Also know that age, obesity, fever, dehydration, heart disease, mental illness, poor circulation, sunburn, and prescription drug and alcohol use can play a role in whether a person can cool off enough in very hot weather.
To be safe and keep those around you safe on extremely hot and humid days, it is important to know the symptoms of excessive heat exposure and the appropriate responses.
Heat cramps may be the first sign of heat-related illness and may lead to heat exhaustion or stroke.
